As a database administrator or developer, deletion operations are one of the tasks we often perform. This article will show you how to delete a table in Oracle database.
Step 1: Determine which table to delete
Before performing any database operations, you should determine which table needs to be deleted. Use the following command to display all tables:
SELECT table_name FROM user_tables;
This command will display the names of all tables owned by the current user (referring to the user who is connecting).
Step 2: Delete the table

- Open SQL Developer and connect to your database.
- Select the table to delete from the object navigation pane.
- Right-click on the table and select the "Delete" command.

Method 2: Use SQL commands to delete tables
In addition to SQL Developer, you can also use SQL commands to delete tables. Follow these steps:
- Open SQL Plus or SQL Command Line Interface and connect to your database.
- Execute the following command:
DROP TABLE table_name;
Please replace "table_name" with the actual table name to be deleted.
- You will receive a message that the table has been deleted.
